3 Claims.

This invention appertains to cutlery and more particularly to a novelrazor of the safety type.

Considerable diiculty is experienced in the use of safety razors in thatthe blades tend to collect dirt and unless blades are thoroughly driedthe same will rust and decrease the sharpness or the cutting edge.

It is, therefore, one of the primary objects of my invention to providenovel means for main- 1@ taining the blade at all times in a clean andsanitary condition and in a dry state, without the necessity of removingthe blade from the holder after the razor is used.

Another prime object of my invention is the provision of novel means formounting the blade within the holder, whereby the blade can be movedinto and out of a projecting operative position b-y manipulation of thehandle, means being provided for automatically wiping the blade duringthe movement thereof into and out of its operative position.

A further object of my invention is the provision of a safety razorembodying a holder having facing resilient wiping pads between which theblade is adapted to be mounted for sliding movement with meansconirolled from the handle for sliding the blade in the holder betweenthe pads, the pads acting to wipe the blade when the blade is moved intoa retracted position in the holder.

A further object of my invention is the provision of use of elastic orresilient pads for gripping contact with the opposite faces of theblade, the pads forming a substantial air and water-tight seal with theblade, whereby only the cutting edge of the blade will be exposed to theaction of the water, when the blade is in its projected position, thecuting edge of the blade being movable between the pads and thoroughly 9wiped after the razor has been used and when the blade is moved to itsretracted inoperative position.

A further object of my invention is the provision of novel means forsliding the blade in the holder between the resilient or exible pads,said means embodying a sliding rack bar for detachably engaging theblade and an operating handle connected with the rack bar.

With these and other objects in View, the invention consists in thenovel construction, arrangement and formation of parts, as will behereinafter more specically described, claimed and illustrated in theaccompanying drawing, in which drawing:

Figure 1 is a side elevation of a razor constructed in accordance withmy invention, the holder portion of the razor being shown in transversesection, the section being taken substantially on the line 1--1 ofFigure 6 looking in the direction of the arrows.

(Cl. Sil-12) Figure 2 is a view similar to Figure 1 showing the blade inits retracted inoperative position.

Figure 8 is a transverse section through the holder taken on the line3-3 of Figure 6 showing the bade in its retracted position.

Figure 4 is a top plan View of the razor with the handle partiallybroken away.

Figure 5 is a fragmentary section illustrating the guide for the lift orrack bar of the razor blade.

Figure 6 is a front elevation of my improved razor.

Referring to the drawing in detail, wherein similar reference charactersdesignate the corresponding parts throughout the several views, theletter A generally indicates my improved razor which comprises theholder l0 and the movable handle 35.

The holder 10 comprises a back or guard plate 1l constructed from anypreferred metal suitably plated or otherwise treated to enhance theappearance thereof. The extreme lower edge of the back plate 11 isoiiset forwardly as at 12 and then bent rearwardly as at 13 to form theguard. The guard 13 and the offset 12 can be provided with slits, ifdesired, to form a substantial guard plate. The plate 11 at itstransverse center and above the offset portion 12 is provided with arearwardly directed struck-out guide portion 14 which forms a channelfor slidably receiving the lift or rack bar 15 for the razor blade 16.

The razor blade 16 is formed in the ordinary manner from thin temperedsteel and the same is provided adjacent to its transverse center with anopening 17 for receiving the forwardly projecting foot 18 formed on theinner end of the lift or rack bar 15. Hingedly connected to the upperedge of the back plate 11 is a swinging front plate 19. As shown, theupper edge of the front plate 19 curves rearwardly as at 20 and isprovided with circular hinge barrels 21 for reception in the slots 22formed on the back plate 11. The lower edge of the front plate 19 curvesinwardly as at 23 toward the back plate but terminates in slightlyspaced relation to the offset portion 12 of said back plate. The sideedges of the front plate are provided withv rearwardly directed sidewalls or flanges 24 which carry suitable resilient clips 25 for engagingover the back plate. This detachably locks the front plate with the backplate. As shown, the guard plate 13 of the back plate is providedadjacent to its opposite ends with forwardly projecting guard fingers 26which receive the lower edge of the blade to limit the outward movementthereof and to prevent injury to the blade by coming in contact withforeign objects.

In accordance with my invention I provide facing pads 27 and 28 formedof resilient compressible material such as rubber and these pads 27 and28 are secured respectively to the inner faces of the front plate 19 andthe back plate 11. As shown, these pads 27 and 28 cover substantiallythe entire inner face of the front and rear plates and extend from oneend of the same to the other and engage the top edges of the plates. Thelower edges of the pads terminate short of the lower edges of the plates11 and 19, so that the cutting blade 16 can extend below the pads whenthe blade is in its shaving position. These pads can be secured in placein any preferred manner, such as by the use of small rivets 29. Thus,one pad is carried by the plate 19 and the other pad is carried by theplate 11. When the plate 19 is swung over the plate 11 to its closedposition, the meeting faces of the pads abut so as to compress the pads,for a purpose which will be hereinafter more fully set forth.

The shaving blade 16 is received between the pads 27 and 28 and the padsare provided with narrow registering slots 30 through which extend thefoot 18 of the lift bar l5. The provision of the slots 30 allows theengagement of the foot 18 with the opening in the razor blade.

The upper edge of the back plate 11 is provided with a rearwardlyinclined supporting arm or bracket 31 having formed on its upper edgethe knob 32. This arm 31 is of a resilient nature and acts as means forconfining the handle 35 in a pre-determined position, as will be laterdescribed.

The handle 35 can be formed in any desired manner, but I prefer to makethe same of tubular construction to provide a hand grip 36. The

forward end of the hand grip 36 is provided with a forwardly projectingarm 37, which is in turn provided with the offset forwardly extendingleg 38. The front end of the leg is provided with a hinge barrel 39 forengaging the upper end of the lift bar 15. The leg 38 is provided withan opening 49 through which the catch or resilient arm 31 is adapted toproject when the handle is in one of its positions. As clearly shown inFigure 1 of the drawing, the knob 32 of the arm or catch 31 is adaptedto snap over the outer face of the leg and hold the handle againstmovement. If desired, the hand grip portion 36 of the handle can beprovided with out-struck annular beads 4l, so as to insure the formingof a proper grip on the handle.

By referring to Figure 5 of the drawing, it will be noted that the liftbar is slidably mounted within the struck-out guide 14 and that the liftbar has its side edges provided with slots 42 which receive the sidewalls of the out-struck guide 14.

By this construction all lateral shifting move` ment of the lift bar isprevented but the same is permitted a free sliding movement toward andaway from the guard plate 13.

In the use of my improved razor, the blade 16 can be placed in positionby raising the front plate 19 and the blade can be laid on the pad 28with the foot 18 extending through the opening 17. The front plate 19can now be moved to its closed position and retained in this positiin bymeans of the resilient catches 25.

When it is desired to shave with the razor, the handle is swungdownwardly which will move the lift bar l5 toward the guard 13. Thismovement will carry the blade 16 to its operative shaving position andthe handle will be held against accidental swinging movement by the knob32 of the resilient arm 31.

The razor can now be handled in the ordinary manner for shaving andafter the shaving operation has been accomplished, the cutting edge ofthe blade and the guard 13 can be washed by holding the same under thefaucet. The knob 32 can now be depressed and the handle 35 is swungoutwardly and the lift bar 15 is pulled outwardly. This will carry theblade 16 between the pads 27 and 28 and move the cutting edge of theblade inward between the pads. The pads will exert a wiping action onthe blade removing all foreign matter therefrom and at the same timeleaving the same in a dry condition. In view of the tight contactbetween the pads, the blade, when the same is in its retracted position,will be confined substantially in an air tight condition between thepads.

By my improved construction of razor only the cutting edge of the bladewill be exposed, when the razor is in use and thus, the major portion ofthe blade is protected from the water.

Obviously, the necessity of taking the razor apart for cleaning theblade after each shave is eliminated and the blade is thoroughly wipedmerely by pulling outwardly on the lift bar. This insures proper care ofthe blade and the consequent long life thereto.

Likewise, the dispensing of the wiping of the razor blade on hand towelsis eliminated and consequently, the' likelihood of cutting the towels iseliminated.

Changes in details may be made without departing frim the spirit or thescope of this invention, but what claim as new is:

1. A safety razor comprising a pair of clamping plates, means foruniting the plates for clamping a blade therebetween, a pair of facingcompressible pads carried by the inner Afaces of the plates, a bladereceived between the pads having its cutting edge movable exteriorly ofthe pads when the blade is in one position for shaving purposes, thepads entirely encasing the blade, when the blade is in another one ofits positions, a manipulating handle, and means for sliding the bladebetween the pads from the handle.

2. A safety razor comprising a back plate having a guard at onelongitudinal edge, a front plate hingedly connected to the otherlongitudinal edge of the back plate, means releasably connecting theplates together adjacent to their free edges, a cutting blade, acompressible pad secured to the inner face of each plate, the pads beingof sufficient size to completely enclose the blade when the same is inone of its positions, the pads terminating short of the free edges ofthe plates, and means for sliding the blade between the pads.

3. A safety razor comprising a back plate having a rearwardly struck-outguide channel formed therein, one longitudinal edge of the back platebeing provided with a guard, a front plate hingedly connected with theother longitudinal edge of the back plate, means releasably connectingthe front plate adjacent to its free edge with the back plate, a pair ofcompressible pads secured to the inner faces of the front and backplates, a blade slidably mounted between the pads having an openingtherein, a lift bar slidably mounted in the channel having a forwardlydirected foot detachably received in the opening, a manipulating handleconnecting with the upper end of the lift bar, and means releasablyconnecting the handle to one of the plates.
